Datasheet AC/DC Drivers PWM type DC/DC converter IC Included 650V MOSFET BM2Pxx2 Series General Description Features The PWM type DC/DC converter for AC/DC provide PWM frequency : 65kHz an optimum system for all products that include an PWM current mode method electrical outlet. Burst operation when load is light This IC supports both isolated and non-isolated Frequency reduction function devices, enabling simpler design of various types of Built-in 650V start circuit low-power electrical converters. Built-in 650V switching MOSFET This IC built in a HV starter circuit that tolerates 650V, VCC pin under voltage protection it contributes to low-power consumption. VCC pin overvoltage protection With current detection resistors as external devices, a SOURCE pin Open protection higher degree of design freedom is achieved. Since SOURCE pin Short protection current mode control is utilized, current is restricted in SOURCE pin Leading-Edge-Blanking function each cycle and excellent performance is demonstrated Per-cycle over current protection circuit in bandwidth and transient response. Soft start The switching frequency is 65 kHz. At light load, the Secondary Over current protection circuit switching frequency is reduced and high efficiency is BR pin AC input low voltage protection achieved. BR pin AC input high voltage protection A frequency hopping function is also on chip, which contributes to low EMI. Package W(Typ.) x D(Typ.) x H(Max.)
